CHEMICAL FORCE MICROSCOPY

摘要: Atomic force microscopy is an imaging tool used widely in fundamental research, although it has, like other scanned probe microscopies, provided only limited information about the chemical nature of systems studied. Modification microscope tips by covalent linking organic monolayers that terminate well-defined functional groups enables direct probing molecular interactions and with sensitivity. This new technique has been to adhesion frictional forces between distinct aqueous solvents. Contact mechanics provide a framework model adhesive estimate number interacting groups. In general, measured follow trends expected from strengths interactions, solvation also plays important role. Knowledge these provides basis for rationally interpretable mapping variety functionalities processes such as protonation ionization.
